  • Publication number: 20200216614
    Abstract: Disclosed is a polyimide film generated from a solution containing a polyamic acid in a high-boiling, aprotic solvent; wherein the polyamic acid comprises one or more tetracarboxylic acid components and one or more diamine components; and wherein at least one of the tetracarboxylic acid components is a quadrivalent organic group derived from a bent dianhydride or an aromatic dianhydride comprising —O—, —CO—, —NHCO—, —S—, —SO2—, —CO—O—, or —CR2— links, or a direct chemical bond between aromatic rings; and wherein at least one of the diamine components is a divalent organic group derived from a bent diamine or an aromatic diamine comprising the same links, or a direct chemical bond between aromatic rings; and wherein R is the same or different at each occurrence and is selected from the group consisting of H, F, alkyl, and fluoroalkyl.

  • Patent number: 10087479
    Abstract: Reaction solutions are disclosed herein comprising water, incompletely refined sucrose, and a glucosyltransferase enzyme that synthesizes insoluble poly alpha-1,3-glucan having at least 50% alpha-1,3 glycosidic linkages and a weight average degree of polymerization (DPw) of at least 100. The yield of poly alpha-1,3-glucan by a reaction solution herein is at least 7% of the weight of sucrose that was converted in the reaction solution. Further disclosed are methods of producing poly alpha-1,3-glucan using incompletely refined sucrose, and poly alpha-1,3-glucan produced by these methods.
